In transduction, genetic material of one bacterial cell goes to other bacterial cell by agency of bacteriophages or phages (viruses, infecting bacteria). Transduction was first of all reported in Salmonella typhimurium by Zinder and Lederberg (1952). Transduction is used for gene mapping and analysis in bacteria and also for strain construction.

Bacterial transduction is a process in which genetic material, specifically genes, is transferred from one bacterium to another by a bacteriophage (a virus that infects bacteria). Among the given options, option A is the correct statement for bacterial transduction.
Explanation:
Bacterial transduction involves the transfer of genes from one bacterium to another through a bacteriophage. Let's break down the process of bacterial transduction to understand why option A is correct.
1. Bacteriophage infection:
- Bacteriophages are viruses that specifically infect bacteria.
- They attach to the surface of the bacterial cell and inject their genetic material (DNA or RNA) into the bacterium.
2. Phage replication:
- Once inside the bacterium, the phage takes over the bacterial machinery and starts replicating its own genetic material.
- The bacterium's resources are used to produce new phage particles.
3. Transduction:
- During phage replication, sometimes the phage DNA mistakenly packages a fragment of the bacterial DNA instead of its own genetic material.
- This can occur if the phage DNA is damaged or if a recombination event happens between the phage and bacterial DNA.
- The resulting phage particles, called transducing phages, carry this bacterial DNA fragment.
4. Transfer of genes:
- When the transducing phages infect other bacteria, they inject the bacterial DNA fragment into the recipient bacterium.
- This bacterial DNA can then recombine with the recipient bacterium's own DNA, leading to the transfer of genes from the donor bacterium to the recipient bacterium.
- The transferred genes can be incorporated into the recipient bacterium's genome and expressed, potentially conferring new traits or functions.
In summary, bacterial transduction involves the transfer of genes from one bacterium to another through a bacteriophage. The phage mistakenly packages a fragment of the bacterial DNA during replication, and when this transducing phage infects another bacterium, it transfers the bacterial DNA fragment, resulting in the transfer of genes. Option A correctly describes this process and is the correct statement for bacterial transduction.
